We are very pleased that Mr. ppa. Dipl. Ing. Sawillion, an expert from the KEA BW, gives us an insight into how to find one's way through the wide range of subsidies. Here the interview:

Dear Mr. Sawillion, Climate protection in construction - a exciting topic that can sometimes overwhelm you. How do I as a find my way through the jungle of legal requirements and subsidies? subsidies? And where can I find all the information under one roof?

On the one hand, we have regional energy agencies in almost all the counties regional energy agencies in almost all of Baden-Württemberg's counties. building owners with advice. A list can be found on our homepage (https://www.kea-bw.de/kommunaler-klimaschutz/regionale-energieagenturen).

Further search aids are offered by our own funding database (https://www.kea-bw.de/foerderberatung).

Zukunft Altbau, the central information and motivational program of the federal state, offers a wide range of additional information on the topic (https://www.zukunftaltbau.de/) and explains the federal subsidy BEG with a current virtual lecture under https://www.youtube.com/watch?v=gMqEIleIv_Y.

Via www.ee-fit.de people who want to renovate existing buildings can learn how to make them for renewable energies and how to renovate them efficiently and and target-oriented.

2. in your experience, what are the biggest levers that we can use to both that we can use in the housing sector to both save CO2 and better equip the city for heat stress, etc., better, and where is the difference between funding provided and drawdown rate the most highest? What do you think that is due to?

There are local measures such as green PV roofs, which contribute to CO2 reduction and have a and have a positive effect on the microclimate. With PV, it's all about making the best use of suitable roof surfaces. roof surfaces in the best possible way. The new PV obligation for new residential buildings in the Baden-Württemberg Climate Protection Act is also aimed in this direction.

In the past, the aim in Stuttgart was to achieve the most homogeneous roof roof views and was therefore critical of PV.

In general, a large savings factor lies in the reduction in per capita living space. Here, the trend is still going in the the other, wrong direction. Municipalities in particular could and should use offer instruments for this purpose, such as an apartment swap meet and facilitate the general conditions for changing apartments. We should not regard this topic as a "nice to have but should be approached professionally. This is particularly true against the background of rising energy prices.

In the case of subsidies, the figures for the number of residents figures show, on the one hand, that the major cities are having a harder time. On the other hand, we see a slight north-south divide with advantages for the south. This is probably mainly structure of the buildings, and of course the availability of capital also plays a role. availability of capital also plays a role.


3) What potential do you see for digitization to make a major climate protection in your own living environment?

Smaller potentials in the order of of 10 percent we see the digitization of heating controls and transparency in the visualization of consumption values the visualization of consumption values or the generation of PV electricity - but However, there is also a risk that improvements in comfort or security will result in the bottom line, more energy will be consumed, thus counteracting climate protection. counteracting climate protection.

These would be classic rebound effects that we should avoid.


That is an excellent comment at the Mr. Sawillion, whom we would like to thank very much for this overview! thank you!​​​​​​​
